Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a lifting rod suitable for a monitoring camera. Background Art

[0002] With the improvement of people's living standards, road traffic conditions are becoming more and more complicated and crowded. Collecting road traffic information with the help of electronic monitoring has become an important means to formulate and adjust traffic congestion countermeasures and ensure smooth road traffic. This shows that outdoor monitoring involves all aspects of our lives. In outdoor monitoring, cameras must use special camera poles, especially monitoring poles.

[0003] After searching, Chinese patent CN212224848U was found and announced a vertical pole for a lifting video surveillance device that is easy to maintain. By turning the detachable hand crank, the height of the cross bar can be freely adjusted, eliminating the tedious operation of using a lift for maintenance. By loosening and tightening the hexagonal screws on the telescopic cross bar with the detachable hand crank, the cross bar can be extended or shortened, thereby achieving the purpose of not obstructing traffic and avoiding the tediousness of maintenance personnel searching for tools. When going for maintenance, only the hand crank is needed, which can achieve the dual purposes of adjusting the height and length of the cross bar at the same time. It can be seen that the The patent realizes adjusting the height of the crossbar to facilitate maintenance and reduce traffic obstruction. However, it is achieved by using a screw, a first bevel gear, a second bevel gear and a thread. The height of the screw is the highest adjustment position, which means that the main rod also needs to be at the same height as the screw, resulting in the main rod and the screw occupying a large space, and the length of the main rod cannot be retracted, which will be inconvenient for transportation. If the hydraulic cylinder is divided into several sections for lifting, it is necessary to control multiple hydraulic cylinders separately, affecting the coordination during the lifting process. For this reason, a lifting rod suitable for surveillance cameras is proposed. Utility Model Content

[0022] In addition, the top ends of the inner walls of the fixed cylinder 2 and the movable cylinder 3 are fixedly connected with a baffle 8, and the convex rib 10 is slidably connected to the baffle 8. Under the sliding cooperation of the baffle 8 and the convex rib 10, the movable movable cylinder 3 has a guiding property, so that the movable cylinder 3 can only move up and down, and the bottom end of the inner wall of the movable cylinder 3 is fixedly connected with a convex plate 9 corresponding to the baffle 8, which prevents the movable cylinder 3 located above from completely detaching from the fixed cylinder 2 and the movable cylinder 3, and plays a role of limiting. The baffle 8 and the convex plate 9 are both annular in shape, and a fixing ring 13 is fixedly installed on the top of the top plate 4.

[0023] See also Figure 2-3 , a synchronous lifting assembly 7 for reducing the space occupied during the lifting process is provided on the fixed cylinder 2, the movable cylinder 3 and the mounting groove 6. The synchronous lifting assembly 7 comprises a hydraulic cylinder 71, a movable seat 72, a movable rod 73, a connecting seat 74, a first telescopic rod 75 and a second telescopic rod 76. The hydraulic cylinder 71 is fixedly mounted on the inner bottom wall of the mounting groove 6. The use of only one hydraulic cylinder 71 is conducive to lifting and can also reduce energy consumption. The movable seat 72 is fixedly mounted on the output end of the hydraulic cylinder 71. The hydraulic cylinder 71 is retracted to push the movable seat 72 to move laterally and gradually perform the lifting work. The cross-sectional shapes of the slide groove 5 and the movable seat 72 are both inverted T-shaped, which prevents the movable seat 72 from moving out of the slide groove 5 and plays a limiting role. The movable rod 73 is hinged to the inner side walls of the fixed cylinder 2 and the movable cylinder 3. The movable rod 73 can rotate on the fixed cylinder 2 and the movable cylinder 3. The inner side walls of the fixed cylinder 2 and the movable cylinder 3 are fixedly mounted with a support seat 12 hinged to the movable rod 73, and the movable rod 73 is hinged to each other.

[0024] In addition, the connecting seat 74 is arranged at the hinge between the movable rod 73 and the movable rod 73. The connecting seat 74 can push the movable rod 73 that is hinged to each other to open or close. The opening of the movable rod 73 pushes the fixed tube 2 to lift up, and the closing of the movable rod 73 pulls the fixed tube 2 down. The first telescopic rod 75 is fixedly installed between the movable seat 72 and the opposite side of the connecting seat 74, and the second telescopic rod 76 is fixedly installed between adjacent movable seats 72. The first telescopic rod 75 and the second telescopic rod 76 themselves have the function of lifting and lowering, which is conducive to adapting to the changes in the spacing between the movable seat 72 and the connecting seat 74 and between the connecting seats 74. Driven by the movable seat 72, the first telescopic rod 75 and the second telescopic rod 76 push the movement of the connecting seat 74 to realize multi-stage lifting of the movable tube 3.

[0025] See also Figure 4-5 A locking assembly 14 is provided on the top plate 4 and the fixing ring 13. The locking assembly 14 includes a support shaft 141, a threaded column 142 and a contact block 143. The support shaft 141 is rotatably connected to the top of the top plate 4. A mounting plate 16 is fixedly installed on the top of the support shaft 141. A camera 17 is installed on the top of the mounting plate 16. The camera 17 can rotate with the support shaft 141. The threaded column 142 is threadedly connected to the fixing ring 13. A handle is fixedly installed on the head of the threaded column 142 to facilitate the rotation of the threaded column 142.

[0026] In addition, the contact block 143 is rotatably connected to the tail of the threaded column 142 and corresponds to the outer surface of the support shaft 141. When the contact block 143 abuts against the outer surface of the support shaft 141, the support shaft 141 can be fixed. When no contact occurs, the support shaft 141 can rotate again. The contact block 143 is adapted to the outer surface of the support shaft 141. A limiting rod 15 slidably connected to the fixing ring 13 is fixedly installed on one side of the contact block 143 close to the fixing ring 13. Under the connection of the limiting rod 15, the contact block 143 can move.

[0027] It can be understood that by rotating the support shaft 141, the mounting plate 16 and the camera 17, the monitoring direction of the camera 17 can be adjusted. Even if the installation angle of the base plate 1 is deviated, the camera 17 can be adjusted. Then, the threaded column 142 is rotated, and the contact block 143 moves toward the outer surface of the support shaft 141, gradually abutting against the outer surface of the support shaft 141, thereby fixing the monitoring direction of the camera 17.

[0028] When this embodiment is in use, the hydraulic cylinder 71 contracts, the movable seat 72 moves, the first telescopic rod 75 and the second telescopic rod 76 move accordingly, and the connecting seat 74 is driven to push the mutually hinged movable rods 73 to gradually open, causing multiple movable cylinders 3 to be lifted under the resistance and push of the movable rods 73, and the upper movable cylinder 3 is lifted on the basis of the lifting of the lower movable cylinder 3, realizing the function of multi-stage lifting, so that it can be lifted to a higher position.

[0029] The beneficial effects of the above embodiments are:

[0030] The lifting rod suitable for monitoring cameras is provided with a synchronous lifting component 7. The synchronous lifting component 7 uses the rear movable seat 72 to pull the first telescopic rod 75 and the second telescopic rod 76 to move. Under the connection of the connecting seat 74, the connecting seat 74 pushes the mutually hinged movable rods 73 to move accordingly, so that the movable rods 73 push the multiple movable cylinders 3 to move together. With the help of the movement of the lower movable cylinder 3, the upper movable cylinder 3 is stretched and moved successively, thereby realizing the multi-stage synchronous lifting function of the movable cylinder 3, and the movable cylinder 3 can be retracted during the lifting process, reducing the occupied space of the synchronous lifting component 7. At the same time, only one hydraulic cylinder 71 needs to be controlled separately to realize the synchronous lifting of multiple movable cylinders 3, reducing the control and ensuring the coordination during the lifting process.
